数据删除任务

• 用户数据范围暨用户id集：wa_users表中的用户id集
• 查询wa_withdraw表中用户id不在用户数据范围内的记录，并写一个删除这些数据的sql

1) 查询核对 SQL

-- 统计孤立提现记录数
SELECT COUNT(*) AS orphan_cnt
FROM wa_withdraw w
WHERE NOT EXISTS (
  SELECT 1 FROM wa_users u WHERE u.id = w.user_id
);

-- 抽样查看前 100 条，核对是否确实需要清理
SELECT w.*
FROM wa_withdraw w
WHERE NOT EXISTS (
  SELECT 1 FROM wa_users u WHERE u.id = w.user_id
)
ORDER BY w.id
LIMIT 100;

2) 删除 SQL

DELETE w FROM wa_withdraw w
WHERE NOT EXISTS (
  SELECT 1 FROM wa_users u WHERE u.id = w.user_id
);

3) 操作备注

• 建议在执行前对 wa_withdraw 做一次备份：CREATE TABLE wa_withdraw_bak_20260423 AS SELECT * FROM wa_withdraw;
• 建议先跑 COUNT(*) 与 LIMIT 100 人工核对，再执行 DELETE
• 全程放入事务中执行，确认无误后再 COMMIT
